Single BL-Ctrl V3.0 2XL
power
voltage : 10 to 30V -> 3 -7S Lipo
- 6 -layer PCB for optimal heat dissipation . 70u copper layers make the entire circuit board to the heat sink .
- current: up to 60A (Peak per BL-Unit)
- current limiting and temperature limiting
Active freewheeling -> less power loss
Fast response with speed control
- rapid acceleration and braking of the propeller. Active and seamless braking gives the speed precisely and quickly on the new setpoint .
- return energy to the lipo when braking. Seamless transition from acceleration to braking
- significantly faster control with speed control
Other Features
- Adjustable motor timing in several steps of 13-28° - compatible with the most common BL motors
- Adjustable switching frequency ( 10kHz - 20kHz )
- PPM to 500 Hz with simultaneous I2C - bus operation for telemetry and data logging
- Software adjustable direction of rotation
- Adjustable current and temperature limits
- Adjustable start-PWM
- Silent Start: test tone at startup can be disabled
Interface
I2C-Bus with integrated opocoupler allows you to put the BL-Ctrl to the end of the rigger - various interfaces for setpoint input ( I2C, PPM ( 500Hz ) , serial)
- Integrated current measurement measurement of the actual current and the used capacity on the Mikrokopter control
- voltage and temperature measurement with data transmission to the ground station and data logging
- 11-bit resolution (2048 steps )
various feedback to the MikroKopter-FlightCtrl ( blocked motor , power limiting , etc. )
- extented configuration options (eg current limit , temperature limit , ...)
- two LEDs per BL-Ctrl (OK and Error )
- all BLCs are already adressed (address 1-8)
- I2C bus access possible in PPM mode - for data logging and telemetry in PPM mode
- status messages are transmitted to the FC ( engine blocks , Current, Self-test error ...)
- current measurement up to 75A per controller
- Convenient configuration of the BL controller via FC
Connections
Top
Bottom
Connection
- Motor
=> A, B, C
- Adressierung
=> by solder Jumper BL-Ctrl (see below)
- Elko
=> connect two capacitors 2x Elko 470µF/35V (Low-Impedance)
LiPo-Connection
=> LiPo plus / minus
- I2C
=> Connect by 3-lines Molex cable or by soldering a 3-lines
cable => do not connect the GND-Line directly to the Minus-line of the BL-Ctrls -> go with the three lines (C, D and GND) to the FC and connect the GND there
=> the easiest way to connect the I2C-Bus is to use the Molex (See also en/Mini8)
- PPM (Alternative)
=> PPM = orange / + = rot / - = braun => up to 500Hz
Dimension
distribution board
See: Mini8-PCB
Adressing
INFO
The adresses can be set in the range beween 1 and 8. If you need adresses 9-12, please contact the shop
Settings
IMPORTANT: To change the Settings of the BL-Ctrl V3.0 you need a Software version since V2.02a (KopterTool, FlightCtrl, NaviCtrl)!
Normally you have not to change the settings! If you have to to it you can do it like described:
open KopterTool
- press button "Strg" on your keyboard and hold it down.
Then "click" "Settings" in the KopterTool.
Now you will see the window of the BL-Ctrl V3.0.
INFO: only if you "click" and activate the single settings there you can change them.
Error codes
The BL V3 performs a selftest during startup (test-tone). In case of an error, these are the blink codes:
- 1 "1" = Shortcut between A+ and B-
- 2 "2" = Shortcut between B+ and C-
- 3 "3" = Shortcut between C+ and A-
- 4 "E" = A doesn't go to high
- 5 "F" = B doesn't go to high
- 6 "G" = B doesn't go to high
- 7 "H" = A doesn't go to low
- 8 "I" = B doesn't go to low
- 9 "J" = C doesn't go to low
- 10 "K" = Overcurrent when switching to low
- 11 "L" = Overcurrent when switching to high
- 12 "Q" = Cross-circuit between low and high
- 15 overcurrent while starting the motor
- 16 error current measurement
- 17 error voltage measurement
- 18 error temperaturen measurement

FAQ
Motor connection
The motors can be connected either on the top-side or on the bottom-side. You can ignore the small (pre-)soldered points on the top-side.
